Topic: AIO noise problems (not the first)

So, I just bought a AIO second hand, and i guess I got the god ol' noise problems that I've seen a bunch of people experienced.
Its sounds like the inside of the PC is amplified into my monitors and headphones.

Tried to insulate the card with electronics-tape.
Also tried to update BIOS (gigabyte z390 designare).
Reinstalled every driver, and uninstall realtek etc.
Have tried to disable c1e-state via throttlestop.
Switched pcie place. Unplugg everything.
Nothing worked.

Mouse and keyboard is bluetooth.

Never experienced anything like this, and I have owned a lot of different interfaces over the years. Even different RME-stuff.

Is there anyone out there who knows how to fix this?

Re: AIO noise problems (not the first)

Try plug the card with pci-e x1 reiser cable
And with pci-e power

I would try to connect the power to different stable 12v psu so the card will sit far from motherboard and powered by totally different power from other componnents than the pc

And plug the cable to the second pci-e slot that comes after the gpu (the x16 long one)

Tell me if the problem solved

Re: AIO noise problems (not the first)

Gotta go get some of this things you mentioned first!
I did try this thing someone mentioned on a similar thread on Gearslutz where you switch a variable on Windows registry, and then switch the idle function on power scheme.  That worked a bit, but not completly!

Tried to measure common ground for the PCIe card also to see where the card gets grounded from. It seems there's a common ground in the pcie connector besides the plate. I get continuity when averything is turned of, which is something I dont really understands.

Re: AIO noise problems (not the first)

Sorry to hear about your problems.
There can be many reasons, by google I found these threads with helpful information.
Some things you tried already but maybe you find something new in the threads to try out.

How about your PSU ??
Can also be PSU related, here the replacement of PSU helped:

Here it was mainboard related:

Noise problems should be gone since around 2010 ... but as you bought second hand

Re: AIO noise problems (not the first)

Hm, I did try to disable the wifi card, and (almost) all of the interference stopped! Maybe thats the solution?

Re: AIO noise problems (not the first)

Sure, WiFi cards are known to cause issue ...

Re: AIO noise problems (not the first)

I was a bit to eager to post a solution. The wifi/network card did not solve the problem!
When I open a DAW (studio one or live 10) the noise gets worse. Its like double the volume of normal windows useage/web surfing.
When I did disable wifi-card, the normal windows useage got better. But it still exist in the daw domain.

If I where to use a adat or AES-converter, would it perhaps maybe kill the noise? Have anyone tried that?

Re: AIO noise problems (not the first)

External solutions do not show this kind of issue, and if then they can easily be solved with the usual ground loop fixes. That is nearly impossible within the computer. An external AD/DA connected via ADAT or SPDIF to the AIO will also not have such noise.

Re: AIO noise problems (not the first)

I received a used RME AIO interface (board version 1.4, firmware patched to latest) with an XLR breakout and I also have some interference issues with my IEM's directly connected to the headphone out (some just by having the computer on, some additional noise by moving the cursor around), but:
My AKG headphones do not have any noticeable interference. Additionally, I have a mini-amp (FiiO E06) and if I plug that on the HP out and then my IEM on it, I lose the interference. How can that be explained? Does the impedance come into play?

Unfortunately I don't have my JBL speakers with XLR-in to test the XLR output, but would there be a lower chance that the interference is present there? If that's the case, would getting a cheap mixer and connecting it with the XLR-outs be a valid solution, in order to avoid getting an expensive ADAT DAC?
